Board-to-board electrical connector assembly

Abstract

An electrical connector assembly ( 1 ) includes a first connector ( 2 ) and a second connector ( 3 ) for mating with the first connector. The first connector includes a housing ( 21 ) and a plurality of male contacts ( 22 ) and female contacts ( 23 ) received therein. The housing includes a mating surface ( 210 ) for mating with the second connector and a mounting surface ( 211 ) for connecting with a printed circuit board. A plurality of parallel slots ( 2101 ) is defined in the mating surface, and therefore a partition wall ( 2102 ) is formed between two adjacent slots. Furthermore, the width of the partition wall is substantially equal to the width of the slot. The male contacts and the female contacts are arranged in both side surfaces of each partition wall, and also in opposite inner surfaces of each slot. The second connector has substantially the same configuration as the first connector.

1. An electrical connector assembly comprising:
 a connector including: 
 an insulative housing defining thereof lengthwise and lateral directions perpendicular to each other; 
 a plurality of parallel elongated slots side by side arranged with one another along the lengthwise direction while each of said elongated slots extends along the lateral direction; 
 plural rows of resilient contacts and plural rows of rigid contacts being alternately arranged along said lengthwise direction; wherein 
 one row of resilient contacts is positioned by one side of each of said slots; and 
 one row of rigid contacts positioned by the other side of each of said slots. 
 
   
   
     2. The connector assembly as claimed in  claim 1 , wherein the row of resilient contacts and the row of rigid contacts sharing the same slot, define two rows of horizontal tails extending toward each other. 
   
   
     3. The connector assembly as claimed in  claim 1 , wherein the row of resilient contacts and the row of rigid contacts separated by a partition wall define two rows of horizontal tails extending away from each other. 
   
   
     4. The connector assembly as claimed in  claim 3 , wherein the partition wall defines a passageway into which the resilient contacts is installed. 
   
   
     5. The connector assembly as claimed in  claim 1 , wherein another similar connector is mated with the connector under a condition that the rigid contacts of the connector are mate with resilient contacts of said another connector and the resilient contacts of the connector are mate with rigid contacts of said another connector.
